Reaction of methylcyclopentane has been studied on different Sn-Pt/Al2O3 catalysts at 520 °C. Catalysts were prepared by using controlled surface reactions creating either tin-platinum or tin-alumina interactions exclusively. Based on the analysis of the yield-conversion dependences it was established that in addition to the consecutive routes for the formation of methylcyclopentadiene and benzene, direct routes should also exist. Formation of benzene can be strongly hindered by simultaneous introduction of metallic tin into platinum and ionic tin into alumina.
